A
Stewart-Haas Racing statement said Stewart, who underwent an initial
surgery to stabilize and clean the injury, will require a second
surgery. The broken leg was his only injury from the crash.

Stewart will stay in the hospital for observation.

"I
told someone to go get my phone or else I was going to get up and get
it myself," a post on Stewart's Facebook page said. "Finally got
reconnected to the world and just want to say thank you for all the
prayers and well wishes. My team will remain strong and I will be back."

Max Papis will fill in for the injured Stewart this weekend at Watkins Glen, SHR announced Tuesday afternoon.

Papis,
who has years of road-racing experience all over the world, will drive
the No. 14 Chevrolet in Sunday's NASCAR Sprint Cup Series race. Papis
drove Stewart's No. 14 car on July 30 during a team test at Road
Atlanta.

Missing
the Watkins Glen race means Stewart will snap a streak of 521 starts
dating back to the 1999 Daytona 500 - his first career Cup race. His
streak ranked 10th all time and was third among active drivers behind
Jeff Gordon (710) and Jeff Burton (613).

After
the flip in Canada, he became irritated with reporters who asked about
the incident prior to Sunday's NASCAR race at Pocono Raceway.

"When
they wreck, they get upside down like that," he said. "That was not a
big deal. ... I guarantee you there were 15 to 20 guys across the
country that flipped just like that this weekend and were just fine just
like we were. If it's bad, we will let you guys know."
